Relationship between compressive, split tensile and flexural strengths of ternary blended concrete

Abstract

The paper presents the relationship among the split tensile, flexure and compressive strength of the ternary blended concrete (TBC) by incorporating the micro silica (MS) and ground granulated blast furnace slag (GGBS). Ordinary Portland cement (OPC) was replaced with GGBS by 20% to 50% by an increment of 10% in combination with each replacement level of MS (5%, 10% and 15%). A total of twelve ternary mixes and one control mix was prepared to determine the strength properties at the age of 28 days for w/b = 0.55. The experimental results are compared with the predicted values obtained from the existing relationships and noticed that the experimental values are within the range of predicted values.
